The sculpt on Obi-Wan appears to be a mix of the two actors that played the wise Jedi in the movies; part prequel actor Ewan McGregor and part Sir Alec Guinness in his iconic "New Hope" role. The piece strongly suggests the Jedi Knight just going into hiding on the desert planet Tatooine. Clues include the retired clone trooper armor on his back, Tusken Raider rifle and gaffi stick (not to mention the desert display base) and most importantly, his name - Ben Kenobi being the title he used during his exile.
